TL;DR: It is shown that a model based on electron-phonon-mediated spin-flip scattering explains both timescales on equal footing and concludes that the ultrafast magnetization dynamics can be well described disregarding highly excited electronic states, merely considering the thermalized electron system.

TL;DR: This work demonstrates optical control of ferromagnetic materials ranging from magnetic thin films to multilayers and even granular films being explored for ultra-high-density magnetic recording, and shows that Optical control of magnetic materials is a much more general phenomenon than previously assumed.

TL;DR: It is demonstrated that all-optical helicity-dependent switching (AO-HDS) can be observed not only in selected rare earth-transition metal alloy films but also in a much broader variety of materials, including RE-TM alloys, multilayers and heterostructures.

TL;DR: In this paper, the authors demonstrate that interlayer transfer of spin angular momentum in specially engineered Co/Pt multilayers speeds up the demagnetization process, bypassing the mechanism responsible for the conservation of total angular momentum taking place in a single ferromagnetic layer.

TL;DR: In this article, the influence of the magnetic and electronic transport properties of the materials on the spin transfer effect in magnetization dynamics is discussed and a modified Landau-Lifshitz-Gilbert equation of motion where the different spin transfer torques are included and discussed their influence on the DW dynamics on the basis of simple 1D models and recent micromagnetic simulations studies.
